Summary:

There are three elementary schools serving grades PK-5 in the 21133 zip code of Randallstown, Maryland, all part of the Baltimore County Public Schools district, which serves a diverse suburban community near Baltimore.

In this area, Church Lane Elementary stands out as the top performer, earning a 3-star rating and ranking in the 53rd percentile statewide—a dramatic turnaround from just two years prior. It leads the zip code in math proficiency (33.3%) and science proficiency (37.2%), and it has the lowest student-teacher ratio (13.7) and highest per-student spending ($22,537). Randallstown Elementary is a consistent 2-star school that excels in English Language Arts, with a 49.4% proficiency rate that exceeds the district average and nearly matches the state average, while also having the lowest chronic absenteeism rate (18.0%) in the area. In contrast, Hernwood Elementary is the lowest-performing school, with a 1-star rating, a 27th percentile state rank, and the highest chronic absenteeism rate (31.1%). Its math proficiency (16.1%) is half that of Church Lane, and its ELA scores (33.1%) lag significantly behind the other two schools.

A key takeaway is that higher spending does not guarantee better results: Hernwood spends nearly as much per student ($21,850) as Church Lane but achieves far lower scores, suggesting that how resources are used matters more than the amount spent. Chronic absenteeism is a clear challenge across the area, with two of the three schools exceeding the district average of 25.6%, and it strongly correlates with lower academic performance. For parents, Church Lane offers the strongest overall academics and recent improvement, Randallstown provides reliable ELA instruction and better attendance, while Hernwood faces significant struggles that may require additional support or intervention.
